Abstract: The internal nanostructure and optical properties of mesoporous silicon rugate filters prepared on different p+ type silicon substrates are compared for applications in biosensing. Chemical derivatisation of the internal surface by undecenoic acid hydrosilylation results in red-shifting of the resonant wavelength of the filter, whereby the magnitude of the red shift is found to be a function of the pore morphology. The pore structure was found to play a significant role during infiltration of protein into the photonic crystal.

 

Keywords: porous silicon; photonic crystal; hydrosilylation; rugate filters; optical biosensors; mesoporous silicon; nanostructure; optical properties; nanotechnology; Australia; pore structure.
